To all whom it may concern Be -it -known that TREMONT W. RIOKEL,

a citizen of the United States, residing at M'c'Allen, in the" county 0i Hidalgd and State" of Texas, has invented certain new and useful Improvements in Window-Sash; Locks; andhe does hereby declare the following to beafull, clear, and exact description'of thefinvention, such as will" enable others ski-lled in'the are to which it apper tains tom'ake and use the 'same', reference being had to the accompanying drawings; and to the lette'rs"and figure olireferenc'e marked thereon, which form a part of this" specifieation.

This invention 'relates'to' new'and usefulimprovements in sash locks" and the object in view-is to 'prod-u'cea simpleandeflioient de'vice of this nature,' and'consists essentiallj in the provision ofmeans for permitting either sash tobelocked or one sash'to" bepartially or fully opened, means being rovided-rout s both sash to be automatrcallylocked when the sash are'closed.

The invention consists of further details of -'cons'truction, combinations and arrange ments-- of part's' 'whichwill be hereinafter fully descr'ibed, shown in the accompanying dr awings andthen specifically defined in the appended claims:

The invention is illustrated in the ac'co e ing movement of the member D' and also serves as a means for preventing any tam pering with the 'm-ember through themedium of an lnstrument from the outside of the window "to cause the san'ie *to be" thrown out of operative relationwvith the other parts of the apparatus? A right angledplate' F is fitted-overthetop of the lower sash over which 'the lateral Patented July 9; 1918.-

proje'ctioirD of the member D has a play,"

said plate being provided for the purpose of protecting thefsash'against which said" pro ectionD contacts whenthe member is swung to its' limit iii-eitherdirection.

A metallic plate H of" the general shape shown in'thedrawings is fastened" to the face of the upper sashand has itslower'end H" bent at 'a right angle extending over a portion of the upper surface of the bottom rail of the upper sash, as shown clearly in" 'Fig. 1 of'the drawings; Said plate H has:

flanges I and'K, formed upon its opposite edges, which'at their lowerends terminate a slight dist-ance'above the 'angled flange-H at the bottom. Said'plate, it will be noted, has

Said member D has a handle D pro ecting -fromithe angled portion'thereof and form's'a convenient means for swinging the member. A'bail-shaped strap E is fastened to the opposite edges of the rail of' thedowersash'and servesto-limit the swing- I and K curve to conform to theshape of the plate. A-central partition L-proj'ects I from said plate forming left' way N open at its upper end, and a right way M which,

near its' upper end, has a transverseparti tion J forming a stop aga1nst "wh1ch the"- It will be noted upon reference'tdFigsQ of the drawings thatthe upper end of the inner partitionL is bent at an inclination? as at O for the'purposeof guiding the end" of the extended portion D into the way- N when the lower sash, aft er'having been raised to its upper 1imit,"is-"closed'.

Aspring T is fastened at itsuppefend to theface oftheplate H- and itslowerend' is free, the said partition L- projecting over the spring a slight distance, as shown clearly in Figs. 1 and 2 of the'draWin-gs. Inclined members Sproj ect from the plate and are'positioned in front of said spring andare provided for the purpose of throwing themember D to an upright position after the'lower sash hasbeen ra1sed'and re-" turned to its starting position. The lower freeend of the spring'serves as a stop to prevent the" lower sashbeingmaised when the'memberDis in a vertical position? In operation, when the member D is in the position shown in Figs. 1 and 2 of the drawings, the sash will be locked. If any attempt is made to raise the lower sash or lower the upper sash, the inner end of the projection D will come in contact with the lower end of the spring. If it is desired to raise the sash part way, the member D is swung to the right, so that when the lower sash is raised the end of the projection D will pass up through the right way M a the drawings. Should it be desired to raise the. lower sash its limit the member D is swung to the left, so that when the lower sash is raised the projection D will enter the left way N. When the lower sash is closed, assuming that it has been raised to its upper limit, the projection D coming in contactwith the curved flange I or the' inclined portionO of themiddle flange, will cause said member D to approach a vertical position, and as the lower sash approaches its closed position, the portion D coming in contact with the left inclined guide way S will cause the member D to assume the position shown in Fig. 2 and after'the sash closes it will be automatically locked. Any attempt to raise the lower sash will be prevented by the portion D coming in contact with the spring. It will be noted that the member D should be held with suflicient friction at its lower end where it is pivoted to the frame of the sash, so that there will be no possibility of the member accidentally swinging to the right or left by jar or some other causes, which would throw said member D in such a position that the sash might be raised.

What I claim to be new is:

1. An automatic window sash lock comprising in combination with the upper and lower sash of a window, a swinging member mounted upon one sash and a plate upon the other, a central partition forming a right and a left way, a spring fastened at one end to the plate and cooperating with said-member to hold the sash locked, and means for automatically moving said member so that it will assume a locked relation with the spring when the sash are closed.

2. An automatic window sash lock comprising'in combination with the upper and lower sash of a window, a swinging member mounted upon one sash and a plate upon the other, a central partition forming a right and a left way, a spring fastened at oneend to the plate and cooperating. with said member to hold the sash locked, said .plate having marginal curved flanges designed to cause said member to swing toward a vertical position when the sash is raised, and means projecting from the plate to swing the member to a vertical position as the sash is closed.

3. An automatic window sash lock comprising in combination with the upper and lower sash of a window, a swinging member mounted upon one sash and a plate upon the other, a central partition forming a right and a left way, a spring fastened at one end to the plate and cooperating with said member to hold the sash locked, said plate having marginal curved flanges designed to cause said member to swing toward a vertical position when the sash is raised, oppositely disposed inclined guide members projecting from said plate and eX- tending over a portion of said spring .and serving to throw the member to a vertical position as the sash is closed.
